Emerson-Brantingham Engineers Leaders 
In Tractor Design for Eleven Years 

Originators of Nearly All the Features Used in 
Modern Design on the Best Tractors 

It is with honest pride that E-B designers 
can look on the tractor industry today with 
the knowledge that Emerson-Brantingham has 
given to the world most of the important feat- 

K-B (Big Four) al Wiiiniiieg Molor C"otit«st in I'HO 

ures that are considered standard construction 
on high grade tractors today. 

Foremost among these is the four cylinder 
kerosene burning tractor motor. In this in- 
stance, although the Eniei'son-Brantingham 
motor has had many imitators, none have 
reached the degree of perfection attained on 
the E-B motor, which has only been made pos- 
sible by the years of experimental and develop- 
ment work spent on it before other Companies 
were manufacturing this type of motor or in 

Second, and not less important is the K-ll 
enclosed multiple speed transmission running 

in an oil bath. This feature alone has saved 
E-B tractor owners thousands of dollars in 
gear repairs and much more in time. 

Another big money and time saver that 
originated on E-B tractors is the heavy duty 
roller bearings with which all h]-B tractors have 
been equipped for years. 

In the early days, ignition was one of the 
bugbears of the tractor industry. 13atteries 
were the old stand bys. Low tension magnetos 
were a little improvement, but batteries were 
still necessary for starting. It was not until 
high tension magneto ignition was installed in 

One 1)1' I hf fiisl liuititrs equipped with Hyatt Roller 
Rearitigs (K-B Big Four 1913) 

E-B tractors and the impulse starting system 
worked out that the old unreliable battery 
system could be discarded.

Like Produces Like— A Tractor Can Be No 
Better Than The Factory That Builds It 

Be Sure the Tractor You Buy is Built in a Factoiy Equipped 
with the Machinery to Turn Out Accurate Work 

Now that skilled labor is scarce, more de- 
pends on the factory than ever. Building 
tractors requires extremely accurate work, in 
many cases down to a thousandth part of an 
inch. Today, with the government calling out 
all America's expert workmen the burden is 
placed squarely on the factory. The Emerson- 
Brantingham Company has always made E-B 
tractors largely with the aid of modern auto- 
matic machinery and has recently added a 
large new addition completely equipped with 
the latest type of machines capable of produc- 
ing the most accurate work with the least man 
power. E-B owners are further safe guarded 
by the most rigid inspection system ever in- 
stalled in a tractor factory. Ill very part, no 
matter how small and unimportant, is passed 
on by the inspection department. Perfect 
parts do not make a perfect tractor, however, 
unless properly assembled, and this is deter- 
mined in the E-B factory beyond the shadow of 

a doubt by two thorough tests. The motors 
are fu'st tested separately on a test block as 
they come from the assembly floor. A second 
test is made on tlu^ completed tractor to make 
sure it is worthv to bear the V^-\^ trade mark.

The Most Power for the Weight and 
Money Ever Offered 

E-B 12-20 Model A A, A Three Plow Tractor with power to pull 
Four Plows in Stubble or Easy Plowing 

Unlike an automobile, a traclor inust not 
only propel iLself, biiL also must have sufficient 
power left to do a reasonable amount of work. 
The amount of this surplus power is dependent 
on two things — the weight of the tractor and 
the friction drag. 

Every extra pound of weight over what is 
actually necessary for strength, saps a little 
power from the motor and reduces its tractive 
efficiency. Besides, you are paying good 
money for fuel to move useless metal. In addi- 
tion, it makes climbing grades more difficult and 
tends to nnre down the tractor in soft ground. 

On the E-B 12-20 Model AA, owing to the 
extreme simplicity and compactness of design, 
which has been patented, we have been able to 
greatly reduce the weiglit and also increase 
the strength. 

Although the E-B 12-20 Model AA is very 
conservatively rated and much more powerful 
than its rating indicates, it w'eighs less than 
the average weight of the ten leading 8-16 
tractors vou are familiar with.

It will do all the work that a r(-asonabIe

its rating an<l liavc powt^r to spare.

E-B patented short coupled 
transmission makes this 
construction possible, INote 
in the illustration how short 
the transniission case is 
and that the rear axle and 
transmission form a single 
unit. All the frame is 
needed for is to conned 
the transmission case with 
the front axle and only Iou^a 
en(nigh to form a nioimt- 
ing for the motor. It also 
greatly reduces the number 
of parts and therefore the 
cost to you. This con- 
struction has many ad- 
vantages. It saves an en- 
ormous weight of useless 
metal that would cost you 

money in the original purchase price of the 
tractor and ever after in fuel to move 
around when your tractor was working. 
The L shape of the front allows the wheels to 
be cramped in, permitting the tractor to turn 
in a radius of 123^ feet.

The front girt to which 
the channels are bolted is a 
single casting of semi-steel 
strong enough to withstand 
any strain to which it 
may be subjected. Tlie

is pivoted to the front girt 
allowing tlie axle free move-

with the center of gravity low en(^)ugh, to work 
on side hills too steep for any ordinary wagon 
to travel with safety. All four wheels track 
and all four wheels run on the unplowcd ground, 
thus getting rid of a very serious complaint by 
some farmers who have used other types of ma- 
chines. The draw bar has a wide lateral adjust-

AU Gears On E-B 12-20 Model AA Tractor 
Entirely Enclosed from Dust and Dirt 

E-B Design also Postively Prevents Gears Getting out of 
Alignment — A Double Insurance Against Trouble 

A sit any tractor owner what part of a tractor 
fails first and in ninety cases out of a 
liundrcd he will tell you the gears. In the 
uvei'age tracLor they cither get out of align- 
ment and break from being mounted partly 
in a ease and partly on the frame or they 
quickly grind themselves out by being left 
open and unprotected from the dust and grit 
which in many localities makes as good a cut- 
ting compound as powdered emery. 

On the EJi f2-20 Model AA you arc abso- 
lutely protected from the danger of these 
troubles. All the transmission gears and rear 

axle are housed in the same oil Light dust 
proof gear case. This gear case is a single 
rigid casting with a removable cover for in- 
spection, so thaL it is absolutely impossible for 
any of the gears or the rear axle to get out of 
alignment, no matter wliat strain th(^ tractor 
frame is subject Lo, as all the bearings are 
housed in the same casting. 

'Vim two master gears and the two dri\'e 
pinions are housed in two dust proof sheet 
steel cases located one on each side of the frame. 
This construction permits all bearings to 
run in oil at all times. All gears are machine

partment of the transmission case. With the 
pulley in this position it is not necessary to 
r(Mnove the thresher belt to move the outfit. 

The pulley shaft runs on heavy duty Hyatt 
Roller bearings and both bearings and 
gears operate in an oil bath. When not in 
use the pulley gears can be disconnected from 
the driving gear, by a simple operation 
so that the pulley will remain idle. Inasmuch 
as the thresher pulley eompartnient is sepa- 
rated from the main part of the transmission

E-B Tractors Always Known as The 
Four Cylinder Line 

The many advantages of the four cylinder motor 

were recognized and adopted by E-B 

engineers eleven years ago 

Assuming that imitation is the sinccrest 
praise the foresight of E-B designers in adopt- 
ing and developing the four cylinder motor 
for E-B tractor power has been amply demon- 
strated in the past year or two. Nearly all 
large tractor manufacturers who have persist- 
ently clung to the old one and two cylinder 
types of motors have finally put out four cy- 
linder models. 

The substitute, however, is never as good as 
the original and the experience gained by the 
Emerson-Brantinghara Co., in the manufac- 
ture of one type of motor for eleven years can- 
not be duplicated. 

The E-B line sLands supreme as the only 
standardized four cvlinder kerosene line. 

Why E-B Designers SelecLed ihc Four 
Cylinder Motor 

1 — Constant power — see diagram at bottom 

of page. 
2 — More elastic power— will deliver power at 

a wider range of speeds. 
'A — Lighter weight for the power. 
4— Practically eliminates vibration. 
5 — More conipact~can be put in smaller space. 
6-^Easier to start. 
7 — Easier to repair. 
8 — More economical of cooling water. 
9 — More reliable under varying conditions 

of service. 
10 — The kind of power plant any auto owner 

can understand and the local garage man 

can repair.

Consider This Well in Bnying A Tractor — 
Is The Motor Accessible 

Look it over carefully aiul be sure you can 
get at every part quickly if need be, for it may 
save you the loss of much valuable time or 
even the loss of a crop. 

Your tractor is often many miles from town 
and on account of its slow speed cannot be 
driven into the local garage and dissembled 
like your autoinobile. You must make any 
repairs that are necessary quickly in the field 
and you don't want to take the entire machine 
apart to gcL at it out there in the dirt whore 
parts are easily lost or covered with dust. 

On the E=H 12-20 Model AA this feature has 
been carefully worked out and ample provision 

has been made for getting at any part of the 
motor. Two large inspection plates are pro- 
vided in the right hand side of the motor base 
which are easily removed. The operator sitting 
comfortably on a small box or block facing 
the motor can make any adjustments neces- 
sary on the connecting rod bearings or even 
remove the pistons. 

Other parts of the motor, although entirely 
enclosed to keep out the dirt, can easily be 
reached. In fact, on the E-B motor it is an 
easy job to remove the cyhnders, as the motor 
is free from the mass of piping and wiring com- 
monly found on tractor motor.

The E-B 12-20 H. P. (S.A.E. Rating) Kerosene Motor 
Is the Last Word in Tractor Power Plant Construction 

Designed by Experts backed by Eleven Years Tractor Experience- 
Built in the E-B Tractor Plant by Automatic Machinery 

The E-B 20 11. P. (S. A. E. Rating) Kerosene 
Motor was particularly designed for operation 
on the E-B 12-20 Model AA Tractor and is 
manufactured in the E-B factory. Purchasers 
of the E-B Model AA Tractors are thus abso- 
lutely protected from the ills of stock motors, 
converted gasoline motors and light weight 
automobile motors. It is a heavy duty mod- 
erate speed four cylinder motor that will pull 
its full load on kerosene twenty-four hours 
a day if necessary. 

It embodies all the advantages of previous 
E-B kerosene tractor motors and many new 
features that cannot be oblained on any 
other motor.

Built for Hard Service 

All working parts are completely enclosed 
and dust tight. The cylinders are cast in 
pairs and are free from the great mass of piping 
and wires so coirunon in some motors and 
can be removed very quickly if necessary. The 
oil casing is provided with two large inspection 
plates and is also split so that by taking out a 
few ca[) sc-rews the whole bottom may be re- 
moved thus exposing the 
crank shaft and bearings 
without disturbing the rest 
of the motor. All the parts 
are designed for hard service 
and ai^e made much strong-

casing to show the oil level. 

An oil gauge is also placed on the dash in 

plain sight of the operator. If the oil pressure 

is too low, or if the oil 

density is too thin, or if the 

oil system is clogged up the 

gauge will not show oil. 
The oil in the crank case 

can be run several days. 

The only bearings on the 

motor that need attention 

every day arc the fan and 

pump bearings which are 

provided with grease cups.

E-B Gear Driven Centrifugal Waler Circulatiiiy Pumi) 

E-B Cooling System Most Efficient 
One of the most distinctive features of E-B 
Kerosene Motors is the coohng system. The 
water spaces around the cylinders are made 
larger than gasoline engine practice demands 
so that the added heat generated by the kero- 
sene will not be injurious. Especial provision 
is also made for water circulation around the 


valves and spark plugs. This is most im- 
portant, as one of the great troubles in the 
ordinary motors not designed for kerosene has 
been with spark plugs becoming overheated 
and causing preignition. The entire cooling 
system has a capacity of 7 gallons. The radi- 
ator is the Modinc Spirex, and the water is 
circulated by a gear driven centrifugal pump. 
The fan is also gear driven (no belt to get 
loose or break) and is provided with a self- 
operating spring clutch so that in any sudden 
change in speed the fan or gears will not be 

A horizontal fly ball throttling governor of 
E-B design and manufacture controls the 
motor speed at all times. The governor and 
hand throttle have sej)arate butterfly 
valves so that the motor cannot be raced. The 
governor is on the inside of the motor case and 
runs in an oil bath. 


^^The ignition on the E-B 12-20 Model AA 
Tractor is the K. W. high tension system with 
the K. W. impulse starting magneto, mounted 
on brass away from the heat of the engine. The 
impulse starter enables the operator to turn over 
tlic motor slowly and get a spark for starting 
the same as if batteries were used. It is not 
necessary to spin the motor.

Not a Makeshift, But a Real 
Kerosene Motor 

There are two general wa\s of burning kero- 
sene, both of which have their advantages and 
disadvantages. One is to run the cylinder ex- 
tremely hot and admit the kerosene into it cold 
in the form of a spray, trusting to the heat of 
the cylinder to vaporize it. This system is 
often wasteful of fuel and the intense heat 
makes lubrication difficult and expensive. The 

Bi;iiiiell K('-ros«ii« (^iirhtirntor 

other method is to heat the manifold and vapor- 
ize the kerosene in that way. This method is 
a make shift used on converted gasoline motors. 
It reduces the power of the motor as the heated 
manifold expands the gas to such an extent 
that the cylinders only get a weak charge. The 
E-B method of burning kerosene is distinctive 
and free from the disadvantages of other gen- 
erally used methods. 

The cylinders and manifold are run com- 
paratively cool, therefore the cylinders get a 
full concentrated charge and lubrication is made 
easy. A special Bennett Carburetor is used 

(the most expensive manufactured) in which 
the kerosene is first vaporized as much as 
possible by means of jets and then thrown a- 
gainst the hot walls of a heated chamber of 
the carburetor which changes the vapor into 
a perfect gas without superheating as is the 
case with a heated manifold. The gas is also 
cooled to some extent by passing through the 
cool manifold. 

The gasoline tank holds 4 gallons and the 
kerosene tank 20 gallons. The fuels arc 
changed or controlled by two valves located 
on the dash. Provision for injecting water 
with the fuel is provided for cleaning the cyl- 
inders and for operating under heavy load. 
The carburetor is equipped with a hot air 
damper controlled from the dash for supply- 
ing the heat in the carburetor. 

Gravity feed to the carburetor is used. 

Bennett Air Cleaner 

The dust from a dry field going into the 
motor through the carburetor plays an im- 
portant part in the life of a motor and if 
allowed to get into the motor will mix with 
the lubricating oil and cut with telling etfect 
on the pistons, rings, cylinder walls and all 
bearing surfaces of the motor. E-B motors 
are amply protected from this b> a Bennett Cleaner which is installed in the air line so 
that every bit of 
air entering the 
carburetor is thor- 
oughly cleaned and 
no dirt or grit can 
enter the cylinder. 

This is an acces- 
sory that is very 
necessary to the life 
of the engine and 
is supplied on the 
E-B 12-20 Model 
AA Tractor as reg- 
ular equipment and 
should lengthen the 
life of your machine 
several years. Ben runt Air cif^nnf^r

as it is possible to make a tractor and witli 
ordinary care will do the work it is designed 
for in a most gratifying way. The absolute 
protection given all working parts and the high 
quahty of the accessories and bearings is an 
insurance to you against excessive wear in any 
part of the machine and a guaranty for a long 

Ease of Operation 

The E-B 12-20 Model AA is a small tractor 
with big power, and was especially designed 
for operation by women or boys. The control 
mechanism is exactly the same as on many 
automobiles and is just as easy to handle. 
The auto type steering column is provided 
with the customary spark and throttle levers. 
The gear shift lever is ball and socket type 
and only one foot pedal is used— a combined 
clutch and brake pedal. 

On the dash are the oil gauge, gasoline valve, 
kerosene valve, hot air damper and water valve! 

A comfortable steel spring seat is provided 
for the operator that gives an unobstructed 
view ahead. 

General Equipment and Finish 

The E-B 12-20 Model AA Tractor is fully 
equipped and assend^lcd ready to start wh(5n

lock hasp is located in convenient position 
under the operator's seat. 1 1 is nicely painted, 

striped and varnished with red body and green 
running gear.

tractor. We take greafpains in the iinish and 
it is all you could desire. 

Extra Furrow Guide

A. furrow guide can he fur-nished as an extra 
at an additional cost that will make the tractor 
self steering while plowing. It is a very simple 
device, consisting of an extension spindle which 
is bolted on to the right hand front wdieel. A 
bent pipe which runs in the furrow is provided 
with a bearing which rides on the spindle, thus 
enabling the pipe to move up and down ver- 
tically to provide for the uneveness of the 
ground and to allow the pipt; to be lifted at the 
end of the furrow. This is accomplished by 
means of a rope running back to the operator's 
seat. This spindle is long enough so that the 
guide can be adjusted for plowing with two or 
more bottoms.
